AUXILIARY FEEDING DEVICE FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Fatent.

Application filed September 15, 1917. Serial No. 191,52

To all whom it may concern:

Be it known that I, JEAN B. BEnooUoxoox, a citizen of the United States,and

a resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in AuxiliaryFeeding Devices for Internal- Combustion Engines, of which the followingis a. specification.

My invention relates to the feeding of engines of theinternal combustiontype and more particularly to an auxiliary device that is connected toand discharges a suitable vapor into: the intake manifold of a gasoleneengine. lhe objects I have in view are to provide a feeding device ofthis character that is both simple in construction and easy tomanipulate and is also one that comprises few parts so that it may beeconomically manufactured and can be sold for a moderate price. It isalso an object of my invention to provide suitable means whereby thequantity of vapor discharged from the device may be regulated oradjusted to anicety and may be turned on or cut ofi whenever desired.Owing to the construction and arrangement of the parts of my device, Iam enabled to attain divers results from its operation. For example, thevapor discharged into the manifold by my device may be charged withWater or gasolene for the purpose of modifying the gaseous mixture fromthe carburetor, or for the purpose of. cleaning the pistons andcylinders, etc., the vapor may be charged with kerosene or a carbonremoving compound,-in fact, any suitable liquid may be placed in thereservoir of my device and the vaporized mixture fed to the manifold.

I prefer to accomplish the objects of my invention by substantially themechanism hereinafter described, whereof a diagrammatic illustration isdisclosed in the accompanying drawings that form a part of thisspecification, wherein,-

Figure 1 is an elevation of my device attached to the manifold of aninternal explosive engine, the latter being shown in a Referring to thedrawings, it will be seen my invention preferably comprises acylindrical chamber or reservoir 5 that consists of a tube or hollowcylinder of glass or other suitable material, the ends whereof areclosed by caps 6 and 7, having flanged edges that extend over the sidesof the tube. The

ratemea a 8, rate. r

lower cap 6 has a screw-thread connection with a post 8, that arisesvertically from the center thereof and extends axially through chamber 5where it is screwed into an internally and externally threaded, boss 9tube and the interior surfaces of the caps in order to prevent leakageand to avoid breaking the glass. A pair of clamping nuts 11 are screwedonto the exterior threads of boss 9 in order to clamp the device to asuitable bracket or other support 12, whereby the feeding device may beconveniently mounted adjacent the manifold of the engine. The upper endof post 8 is bored to provide an L-shaped passage .rG the shorter orlateral portion .2? whereof opens into the chamber 5, adjacent the topthereof or above the liquid level, while the longer vertical portion Gof said passage conununicates with the boss 9 or the top of cap 7.

Adjacent the boss 9 isan air inlet device that consists of a pipe 13that is enlarged and threaded adjacent'its upper end and tapped into athreaded boss 1 f also arising from the upper surface of the top cap 7.The lower end of pipe 13 is cut obliquely, as shown, and terminatesadjacent or above the bottom of chamber 5 in order that its end will beimmersed in the fluid or liquid that is contained in said chamber, whilethe opposite or upper end ofv said pipe is provided with an inlet cock15, the adjustment of which latter regulates the quantity of airadmitted to the chamber 5.

A suitable elbow 16 is tapped into the outer end-of the bore of boss 9and has its lateral member connected by means of a sleeve nut 17 to asuitable discharge pipe 18, with which it communicates. One member orbranch of an elbow 19 is connected by a sleeve nut 20 to the oppositeend of discharge pipe 18, while the other branch or member of said elbowis tapped into a suitable threaded inlet opening made in a convenientportion of the manifold B of theengine A. In order to permit thedischarge of the vapor from the chamber into the manifold and to preventback pressure reaching the chamber 5, I have provided a suitable checkvalve 22, which I have shown as being disposed upon the elbow 16, but itwill be understood it may be mounted at any convenient place in thedischarge passage between the chamber 5 and the manifold.

In operation, the chamber 5 is filled with a suitable liquid by removingthe air inlet device, and after the cylinder has been filled to asuitable height, said inlet device is screwed into position again andthe cock 15 is adjusted to permit air to enter therethrough and into thechamber. The suction from the manifold will cause the air to bubble orsurge through the liquid from the lower end of pipe 13 and rise or passout of the liquid charged with a vapor, where it will be drawn offthrough the L-shaped passage mG that is located above the level of theliquid. The vapor will then be drawn through pipe 18 past the checkvalve and into the manifold. When kerosene is used in the chamber 5, thevapor produced by the bubbling of the air through the same will beutilized in cleaning the valves and pistons of the engine, and likewisewhen the cham- .ber is filled with carbon remover, the vapor therefromwill assist in keeping the'cylinders of the engine free of carbonaccumulations. In fact, the device may be employed for modifying thefeed in any manner through the graduated control of the introduction ofair or vapor.

It will be understood that I do not limit myself to the precisestructure disclosed herein, for it is obvious that divers modificationsmay be made without materially departing from the spirit of myinvention. All such changes are contemplated within the scope of myinvention as expressed in the appended claims.

What I claim is 1. An auxiliary feeding device for internal combustionengines comprising a cylinder, closures for the ends of said cylinder,means extending between said closures adapted to clamp them upon theends of said cylinder, said upper closure having an outlet passagewaytherethrough and an inlet port, a pipe mounted in said inlet port andextending from adjacent the bottom of said reservoir to the outside ofsaid upper cap, a regulating cock on said pipe outside said reservoir,and means for establishing communication between the outlet port in saidupper cap and the inlet manifolds of the engine.

2. An auxiliary feeding device for internal combustion enginescomprising a cylinder, caps closing the ends of said cylinder, a centralpost having threaded connections with said caps, said post having an L-shaped passage leading from adjacent the lower face of the upper. cap tothe exterior of said cylinder, a port in said upper cap, a pipe mountedin said port and extending from adjacent the bottom to the outside ofsaid cylinder, a regulating cock on said pipe outside of said cylinder,a hollow stub on the upper surface of said upper cap and communicatingwith said L-shaped passage, bracket clamping nuts threaded on said stub,a discharge pipe screwed into said stub and establishing communicationbetween said L- shaped passage and the manifold of the engine, and acheck valve in said discharge pipe adjacent its connection with themanifold.
